1.1 本试验方法涵盖了测定缓冲弹性地板覆盖物对掉落的尖头物体（如餐叉）刺穿阻力的实验室程序。 1.2 本试验方法使用一个35g圆柱形省道，省道带有一个扁平的小直径尖端，并将其落在地板样品上。省道代表典型叉的重量，尖端产生类似于叉掉落造成的刺穿。 1.3 磨损层较厚的地板即使在最严重的跌落下也不会刺穿。虽然可以通过增加落镖高度或镖的重量来获得数据，但这种数值并没有实际应用。 1.4 以英寸-磅单位表示的数值视为标准值。括号中给出的值是数学转换为SI单位，仅供参考，不被视为标准单位。 1.5 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 具体预防措施说明见 8.2 . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 今天使用的大多数软垫弹性地板都是在家庭厨房中使用的。 厨房地板经常受到餐具和切割刀掉落的危害，这可能刺穿缓冲弹性地板的耐磨层。嵌入这些穿孔中的食物和土壤通常无法通过日常维护清除，从而造成难看的痕迹。渗入垫层的水分、油脂或油可能会渗入泡沫中，导致永久变色。最终，材料的使用寿命缩短。

1.1 This test method covers the laboratory procedure for determining the resistance of cushioned resilient floor coverings to punctures from dropped pointed objects such as dinner forks. 1.2 This test method employs a 35-g cylindrical dart with a flat, small-diameter tip that is dropped onto a specimen of flooring. The dart represents the weight of a typical fork and the tip produces a similar puncture to those which result from dropped forks. 1.3 Flooring with thick wear layers may not puncture under even the most severe drop. Although data can be obtained by increasing the drop height or the weight of the dart, values of this magnitude have no practical application. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precaution statement see 8.2 . 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 Much of the cushioned resilient flooring in use today is in household kitchens. Kitchen flooring is frequently subjected to the hazard of dropped tableware and cutting knives, that can puncture the wear layer of cushioned resilient flooring. Food and soil that become embedded in these punctures often can not be removed by ordinary maintenance, resulting in unsightly marks. Moisture, grease, or oils that penetrate to the cushion layer can be wicked into the foam and cause permanent discoloration. Ultimately, the service life of the material is shortened.
